tion with the drawing, in which,

In all slicing machines of this type, nowon -chine with my inventionapplied thereto taken on line 22 of F igfil trated in this application,a knife of "large p Y I ,7 v

7 h igi 8' 15 an enlarged verticalsection taken diameter is used,whichisnecessary due to the fact that the ax s of the knife of such alira-chine 1s either fixed withregard to the "on line3-31 of Fig. 1 andM i Fig; 4- is a section siinilarto that shown in Fig. 2, but the chainhousing,"which supports above the axis ofthedrive sprocket for the knifeand its chain, and the knife axis is only swingable'on the axis of saidsprocket, hnt is 7 not movable longitudinally of thFhasc, but constantlyretains the radialdistanceffroin' in combiiiationwith"i l ng niac hineof sition, thus bringing the knife edge nearer the adjacent side or edgeofthe movable table.

whereonis'mounted a chainhousi'ng 11 used for supporting a rotatablecircular knife 12. Said base is also provided*witl1"guide rods 13 onwhich a reciprocating-table 14 moves to sprocket; and no provision isn'adeforuse of thesame results and for properly slicing material to thesame effect as 1s done with their large knife. Th1s ob ect1onis overcomew th feeding material "to the forward side "16 of table as ittravels-adJacent said knifej In the modern slic ng machines; the circuinFig. 1, and as may he observed therein, the, center axis of the knife isplaced forward" from the verticalline through theaxis of the; drivesprocket. This arrangement makes it; k 1 a v hasits peripheral edgesharpened at theconto); side, as b'estfshown in'Fi'g. 3, toflplacethecuttingedge adjacent thesi'de of table 14, and with such dished knivesthe plane ofthis cutting edge is generally placed parallel with sc dsideA'G; Whilewitha flat knife the plane ofthe knife nrust be placed atan angle to said from the vertical lineextendingthroughthe center axisof the drive sprocket; and thus with my improved mounting means Iutilize and purpose as the knife of larger diameter A with thefusualmounting means provided on and beveled edgecutastraight slice frointhematerial, her-arise "theknife gets thickeri from the slnirpperipheraledge towards its center.

Another object isto variouslyu adjust the g I therefore provideyan adustaible mounting knife and its'supportingmeans so as to coininoderndishedand 'co'ncaved knife may he used 1 and mounte'djparallel to thetable side 16, or aflat knifeinay also beused'wit-h my mounting meansand mounted at an angle to said table side 16, as best shown in Fig. 4.Furthermore the knife edge wears'downwith constant use and the repeatedsharpening thereof thus decreasing the diameteri ofthe knife, so I alsoprovide my mountingmeans the knife edge, both radially and axially withrespect to the movable table; and also to provide for use of knives ofdifferent shapes and convexity, and for mounting and adjusting the planeof the cutting edge of said knife either parallel to or at an angle withthe side of the movable table, so as to utilize either a convex knife ora flat knife; and a further object is to mount the chain housingadjustably on the base so as to compensate for and to take up slack insaid chain.

Other ob'ects and advantages are accomplished with my invention, as willbecome apradially nearer to the approaching tableto my adjustablemountingsmeans is arranged F ig. 1 is a side elevation of a slicingjniasFig. 2 is an enlarged v, horizontal i section In the'drawing'l haveshown my invention known construction, which includes a base 10 p andfro past said knife and carries a feed plate or material holder '15 forgradually mean'sfor saicl knifeso that either theiusual so that theknife may be moved and adjusted "Jill 1e knifo,is shown in a slanting ortilted po-r lar knifeis usually' dished oreonqav'ed and v table side 16in orderjtohave the sharpened compensate for su'chwear; And in addition,d

to adjust the knife axially to further compensate for the receding ofthe knife edge in an axial direction, as best shown in Fig. 2. All

this adjustment "to compensate for such Wear, etc., I accomplish in avery simple an d inex pensive manner, and at the same time in anentirely practical and "efiici'ent manner; pref erab'ly by providing thechain housing 1'1,

' threaded into openings21 in the adjacent top,

which acts as a knife support, with horizontal supporting flanges 18,and resting these upon the topof base 10, and further providing theseflanges with enlarged openings or-slots 19 through Which loosely extendbolts 20,

of base 1 0. I further place a disc or washer 22 between the head of abolt andthe flange 1'8, on oneside'of said chain housing, and a 7 likewasher between't-he head of a similar'bolt 20 and the bottom plate 24 ofan M11 25 which supports the knife. guard 26' and rests on the flangeatthe other side ofsaid, housing, toaid in clamping thefl anges firmly inposition.

By loosening the bolts 20 theknife with its v support, namely the chainhousing, maybereadily moved and'adju'sted axially of the knife as wellas radiallyof said knife, as indic ated in dot and dash lines in Fig. 2,to

, provide for a new knife or fora knife of 5 greater onvexaaand aftercontinual use to Plate/ 15v m iin' ed t r ii i- Thisadjusable mountingalso "provides means for taking up a certain amount of slack in thechain 29 by .moving the chain housing 11 longitudinally jf, thebase, asindicated in dot and dash lines in Fig. 2 by bringing the drivensprocket (not shown) on the knife shaft 2 7 at'tlie upper part ofthehousing ll, forward and further out of vertical alinement with theIOWQI? i p t'28- What Iclaim as my invention and desire to secure byLetters Patent-isi p I p 1. a In a slicing machine having a rotarycircular knife and a tablernovable one wit-h respect to the other, meansfor adjustably mounting said knife with respect to said table to placethe plane of the cutting edge of said knife at different angles withrespect to the edge of said table.
